My game is extremely laggy and I cannot even play it, it is not my hardware as I have been running borderlands 2 on full high just fine, anyone else have this problem?

I've just got the game and after installing it I get that error message when I press 'play'. Perhaps it has something to do with my computer configuration but all the other games run OK, so I just wanted to know if someone else has this problem and if anyone knows how to fix it, before contacting support. Thanks....

I have an XBox360 controller for PC, and it doesn't work ingame! It does work for the menus, but even if I'm redefining keys I'm not able to use either analog stick or the POV cross (the cross buttons at the left side).

I just got the not turning blue in the unicycle level-achievement (mostly because I thought that was the only way to solve it, heh), but it doesn't show up in the achievement list. The first one I unlocked doesn't show up there either. It's on the actual game page in the library, but not in my profile. Generic Steam problem or something specific to this game that can be sorted?...

Is this game Free 2 Play?
